Using wireshark in packet analysis. Create a display filter for the subnet address of the IPv4 address 66.235. 143.121/16 (Hint: calculate the subnet address on which 66.235.143.121 exists by converting the decimal of this IPv4 address and the subnet mask to binary and using the AND operation) 1. Provide the expression syntax for the display filter created.
The display filter expression for the subnet address of the IPv4 address 66.235.143.121/16 would be: ip.addr == 66.235.0.0/16
To create a display filter for the subnet address of the IPv4 address 66.235.143.121/16 using Wireshark, we need to calculate the subnet address and then construct the filter expression accordingly.
First, we convert the decimal representation of the IPv4 address and the subnet mask to binary.
The IPv4 address 66.235.143.121 in binary is 01000010.11101011.10001111.01111001, and the subnet mask /16 (which represents 16 network bits and 16 host bits) in binary is 11111111.11111111.00000000.00000000.
Next, we perform the logical AND operation between the binary representation of the IPv4 address and the subnet mask.
This operation sets the host bits to zero, resulting in the subnet address. The result of the AND operation is:
01000010.11101011.00000000.00000000
Finally, we construct the display filter expression using the subnet address. The display filter expression for the subnet address of the IPv4 address 66.235.143.121/16 would be:
ip.addr == 66.235.0.0/16
This filter expression instructs Wireshark to display only packets with an IPv4 address that matches the subnet address 66.235.0.0/16.
It filters out any packets with different network bits in the specified subnet range.
By using this display filter, you can focus your analysis on the specific subnet and observe network traffic relevant to that subnet, which can be useful for troubleshooting, monitoring, or analyzing network behavior.

In GW-BASIC, programmers could write and execute computer programs using a simplified and user-friendly syntax. It provided a range of commands and functions that allowed users to perform various tasks, such as performing calculations, creating graphics, and handling user input. The language was primarily text-based, with a command prompt interface where users could enter their programs and execute them line by line.
One of the key features of GW-BASIC was its ability to create simple graphical displays using basic shapes, colors, and text. This made it popular for developing simple games and interactive programs. Additionally, GW-BASIC supported file management, allowing users to read from and write to external files, which expanded its capabilities beyond just interactive programming.
GW-BASIC was often bundled with early personal computers, such as those running the MS-DOS operating system. It provided an accessible way for users to explore the world of programming and develop their skills. Many programmers who started with GW-BASIC went on to learn more advanced languages and pursue careers in computer science and software development.

Write a program that:
1. Declares a boolean variable called my_bool
2. Initializes it to the boolean value of true
3. Prints the value of my_bool.
4. Re-assigns my_bool to the value of test
5. Prints the value of my_bool
Remember that the print value of true is 1 and the print
value of false is e. You should NOT use boolalpha << in
your code!
Here's a program that fulfills the requirements you mentioned:
```cpp
#include
int main() {
bool my_bool = true; // Declares and initializes my_bool to true
std::cout << my_bool << std::endl; // Prints the value of my_bool
bool test = false; // Declares and initializes test to false
my_bool = test; // Re-assigns my_bool to the value of test
std::cout << my_bool << std::endl; // Prints the value of my_bool
return 0;
}
```In this program, we declare a boolean variable called `my_bool` and initialize it to `true`. Then, we print the value of `my_bool` which is `1`. Next, we declare and initialize another boolean variable called `test` to `false`. We re-assign `my_bool` to the value of `test`, which means `my_bool` now holds the value `false`. Finally, we print the value of `my_bool` again, which is `0` (since the print value of `false` is `0`).
